A daily job keeps the tools behind the deb and rpm repositories current

The box updates the tools that build packages.arasaka.software every morning, and
packages.yml rebuilds and re-signs the apt and rpm repositories when those tools change,
so a broken update shows up the same morning, not at the next release.

+  `deploy/packages.arasaka.software/`). It upgrades only those packages, from Ubuntu's updates and security
+  fixes, with package lists of its own, so it never brings the rest of the box forward. There is no two-week wait,

+  the morning's update failed (it reads the result with `systemctl show`, which needs no rights), then runs this
+  script with no version. When the tools' versions or this script differ from what the live repositories were built
+  from (`built-from` beside each snapshot), it rebuilds and re-signs both from the current pools with no new package,
+  swaps the links and checks the live site; otherwise it says "nothing new" and names the versions. Unlike
